MacDonald Mines Exploration Ltd. announces that it has begun a core sampling program at its Wawa-Holdsworth Project. The Company is also solidifying its position in the Wawa Gold District and has staked 84 hectares, approximately 10 kilometers southwest of the Wawa-Holdsworth Project (Figure 1).
Details of the Core Sampling Program
The Company has begun a systematic analysis of core from the 2008 Drill Program. It is developing a database of the lithological and geochemical signatures associated with high grade gold assays by utilizing XRF, magnetic susceptibility and SWIR measurements.
Initial observations found that the highest grades of gold are associated with deformed quartz-iron-carbonate veins, with additional sericite, chlorite and tourmaline alteration, hosted in mafic metavolcanic rocks. These veins locally contain visible gold, accompanied by chalcopyrite, galena and pyrite mineralization.
The Company will be assaying any previously un-sampled prospective zones, particularly those containing significant shearing and quartz-iron-carbonate veining, and re-sampling any significant quartz veins and analyzing them using metallic screening.
Highlights from the 2008 Drill Program include:
|28.35 g/t gold over 1.07 m|
|17.9 g/t gold over 0.54 m|
|13.5 g/t gold over 0.66 m|
|4.07 g/t gold over 0.95 m|
|4.03 g/t gold over 0.90 m|
Wawa-Holdsworth Oxide Sands
The Oxide Sands are one of the main gold targets on the property. Gold mineralization occurs in black sands composed of fine quartz, non-magnetic iron oxides (likely oxidized pyrite) and free gold. The Oxide Sands are interpreted to be derived from the weathering of an auriferous and pyritized Algoma-type iron formation.
The pyritized iron formation is, so far, traced on the property over a 2 km-long strike length.
In 2002, a detailed and systematic sampling of the Oxide Sands was conducted over a strike length of 332.5 metres (Blocks A and B). The mineralized sands reached a depth of at least 8 metres and contained an average gold grade of 3.45 g/t and an average silver grade of 29.99 g/t.
Results from the 2002 Sampling Program:
Preliminary metallurgical testing on Oxide Sands composite samples recovered, without crushing, between 69% and 98.7 % gold. The Company has identified the Oxide Sands as a short-term target for gold production and is anticipating that additional Oxide Sands zones can be discovered along the 2 km strike length of the pyritized iron formation defined so far on the property.
MacDonald Mines will be conducting a geophysical EM survey to map the lateral extents of the oxide sands which will then be used for a more extensive sampling program.
New Land Position in the Wawa Gold District
MacDonald Mines is solidifying its position in the Wawa Gold District (Figure 2.). The newly staked claims host a pyritized iron formation showing similar to the gold targets identified at the Wawa-Holdsworth Project. The staked claims encompass the MILE 12 OCCURRENCE in which the carbonate iron formation is partially pyritized. The Company believes these are the indicators of the circulation of sulfur-rich fluids that can also transport and deposit gold (similar to Wawa-Holdsworth). The geological environment, rich in iron is highly favourable to trap and concentrate gold.
